The U.S. and E3, joined by nineteen other IAEA Boards of Governor members, issued a joint statement expressing concerns over “the Director General’s latest report… [which] concludes once again that the safeguards issues related to three undeclared locations in Iran remain outstanding due to insufficient substantive cooperation by Iran with the Agency”. They urged Iran “to act immediately to fulfil its legal obligations and, without delay, take up the Director General’s offer of further engagement to clarify and resolve all outstanding safeguards issues”. The U.S. envoy also told the Board that “Iran continues to escalate its nuclear activities, including by expanding its enrichment capacity”, adding: “Iran’s production of highly enriched uranium up to 60 per cent has no credible peaceful purpose”. She further asserted: “We stand ready to quickly implement a deal on a mutual return to full implementation of the JCPOA. What we lack is a willing partner in Iran”.
